You have a small tree in your yard that is the height that you want it, but does not have as many branches as you want. Now that you know about auxin’s role in branch activation, how can you prune your plant to trigger it to increase the number of branches?

5. Pick one plant organ that can serve as either a sugar source or a sugar sink, depending on the context. Explain a reasonable situation in which that organ might be a sugar source, and a different situation in which that same organ might be a sugar sink. (1-2 sentence limit for each situation) 

Which of the following answers most accurately summarizes statistically significant (P=0.05) differences in the data in the table below? Table: Z-test analyses of the effects of gibberellic acid (GA) and abscisic acid (ABA), each at two different concentrations, on seed germination of two species after 7 days. 100 seeds of each species were in each treatment group. Name of Plant Species Di H2O 10-6 M GA 10-4 M GA 10-6 M ABA 10-4 M ABA Geranium germination % 96 81 84 88 24 Geranium Z-value 1.48 1.23 0.97 3.89 Geranium Z-value probability (p-value) 0.14 0.22 0.33

The Earth, unless we ruin it, will last for how many more years in its current state in the wondrous Solar System?

2. Stomata embedded in the leaf next to other epidermal cells are critical for water transport up and down the plant’s stem. In the guard cells of a stomatal complex in a leaf sample from your plant, you determine ΨS = -12, and ΨP = 9. In the adjacent subsidiary cells, you determine ΨS = -14 and ΨP = 7. Will the stoma open or close? Explain your reasoning. (3-4 sentence limit)

Had enough yet? Of course you haven’t, we’re just getting started…   Why are plants so skinny? They only eat a light snack.
